Hello,
You may navigate to "View Configuration" panel -> View options and in there enable or disable the "Via Nets" and "Via Span" option buttons to show or hide the Nets names and Via span (or Via numbers as u mentioned. 🙂).
Attached a snapshot for reference..
Basically those "via numbers" are "Via span" that displays what layers a via is connecting.. Once you work on HDI design this will really come in handy.
